Title: Multilayered light guide
Inventor: WATANABE KAZUKI
IPC: G02B6/122
Filed: 1988-03-10
Abstract: PURPOSE:To easily constitute light guides having a prescribed equiv. refractive index by depositing >=2 kinds of materials having different refractive indices on a substrate and forming the multilayers thereof at the thicknesses sufficiently smaller than the wavelengths to be used. CONSTITUTION:This light guide has the light guides of the prescribed refractive indices constituted by laminating the thin films of >=2 kinds of the materials having differences in the refractive indices to the prescribed thicknesses smaller than the light wavelengths within the respective materials on the substrate. For example, a light guide clad 2b is formed by vapor deposition, etc., on the substrate 1 and the layers 2c consisting of GeO2.SiO2 and the layers 2d consisting of SiO2 are alternately laminated thereon by vapor deposition, etc., by which the light guide core 2a is formed. Designing of the refractive index of the light guide and the difference in the refractive index between the light guide core and the light guide clad to prescribed values is thereby enabled and, therefore, the light guide is so constituted as to decrease connection loses at the time of connection to optical fibers.

IPC: C01G39/02
Filed: 1987-03-12
Abstract: PURPOSE:To obtain high-purity molybdenum dioxide at relatively low temperature, in a short time and inexpensively, by adding hydrazine or ascorbic acid and a water-soluble organic solvent to an aqueous solution containing a molybdate and reacting the solution with pressurized hydrogen. CONSTITUTION:Hydrazine or ascorbic acid and a water-soluble organic solvent (e.g. methanol) are added to an aqueous solution containing a molybdate. Then the solution is reacted with pressurized hydrogen to give molybdenum dioxide. Consequently, in producing molybdenum dioxide by using the aqueous solution containing a molybdate and pressurized hydrogen, since hydrazine or ascorbic acid as a reducing agent is added to the aqueous solution and then the water component-soluble organic solvent is added, conventional reaction temperature of 600-800 deg.C can be lowered to about 250 deg.C. The reaction time requiring 8-10hr is shortened to about 2-3hr and therefore consumption of hydrogen can be reduced.

Abstract: PURPOSE:To decrease the duty of the display of an LCD and increase the contrast of the display of the LCD by putting an address space in reverse longitudinal/lateral relation and forming a laterally long address space for access to a display memory from an LCD control circuit. CONSTITUTION:A CPU 1 reads a character to be displayed out of a character generator 2 and writes it in a display memory 4 through an address control circuit 3.
